WebRender newsletter #36

Hi everyone! This week’s highlight is Glenn’s picture caching work which almost landed about a week ago and landed again a few hours ago. Fingers crossed! If you don’t know what picture caching means and are interested, you can read about it in the introduction of this newsletter’s season 01 episode 28.
On a more general note, the team continues focusing on the remaining list of blocker bugs which grows and shrinks depending on when you look, but the overall trend is looking good.

The mercurial history points to https://bugzilla.mozilla.org/show_bug.cgi?id=678859 which was an issue with a very large amount of tiny layers causing the allocation of a very large amount of small textures and that tends to have memory and CPU overhead (depending on the hardware/drivers).
In WebRender, blobs and images in general are packed into larger textures so creating many tiny blobs won’t have this problem.
